To all whom it may concern:

Be it known that We, JOHN WV. MAUGH- Men and RALPH O. Ann-IAN, citizens of they turn of the tractor may be effected, said means being easily operated and being sinipie in cmistruction and elticient in. operation.

With the foregoing and other objects in View which will appear as the description pYOC-CCtiS, th invention resides in the combi nation and ai'rangeinent of parts and in the details of construction hereinafter described and claimed, it being understocxl that changes in the precise eml'iodinient, of the invention herein disclosed, can he made within the scope of what claimed, without departing from the spirit of the invention.

in the accompany" drawings the pre-- ferred form. of the inve on has been shown.

In said drawings: ---lligure 1 is eplan view of the tractor, the motor and the mechanism propelled thereby being removed. Fig. 2 is :1 side elevation of the parts shown in Fig. 1.

Referring to the figures oy characters of reference '1 designates the drive wheels of the tractor, the sumo being connected by an axle 2 which is driven by any suitable mechanism not shown. Moiuited on this axle is frumc ilpreternhly of the form shown and in whi h is coin-ed a. cross bar or spider pivots-Hy connected to the center thereof, as slmwu at .3. This beam has steering chains 7 or other flexible elements secured thereto at. :1 point between its ends and extending from oppos' e sides thereof, these flexible elements being brought into engzigement with guide sheaves 8 mounted upon the rear corner portions of the frame 3. From these sheaves the flexible elements 7 extend to spools 9 which are secured to a transverse shaft 10 carried by the frame 3. wheel ll mounted on this shaft and is engaged by 1 worm 12 fanned upon or secured. to an upwardly estending steering A Worm shaft 13, this shaft being provided with a hand wheel 14 or the like whereby it. can be readily rotated by the operator. It is to be understood-thetthe flexible elements 7 so connected to the spools 9 that when one of them is being wound. upon one spool, the other connection 7 is being unwound, Thus it will be seen that the beam 5 can be swung toward the right or left as desired.

The rearend of the beam is adapted to be connected to 21 supporting element such as s wheeled plow, a mowing machine, a cultivator, or, as in the present instance, a. steering Wheel.

its lower end While its upper end is provided with n-laterally extending arm 17; Pivotally connected to the free end of this arm is a rod 18 which extends diagonally across the beam 5 and 1S pivotahy attached, at its front end, to one side of the. frame 3, as

shown at 19. A wheel 20 is journaled within the fork 16 although it is to be understood -86 is extended straight renrwardly from the .85

frame 3, the machine will more straight for- Ward. When, however, it is desired to turn the machine, shaft 10 is rotated in one direction so as to cause one of the flexible elements 7 to be Wound upon its spool and the 9G other element 7 to be unwound, Thus beam 5 will be swung to, the right or to the left-'21s desired and, by reason of the connection between arm 17 and frame 3, the fork 116 will not; only be swungtoward one side of $5 the machine but will, at the sometime be SW1!!!" about the lon itudinal axis 0 1';- the y b Thus the entire machine can make 7- stem 15. a more abrupt turn than would be; osslble should the axis of the Wheel 20 be ispose-zl at all times at right angles to the longitudinal center of the beam 5.

What is claimed 1s:--

1. In a tractor the combination with e a wheel supported frame, of a beam extending rearwardly therefrom, a stem extending up} wardly through the rear end portion of the beam and mounted for rotation, n soil engaging element connected to the stem, a

member extending laterally from the stem, 11

an obliquely disposed connection between said member and one side of the frame, said are 60 In the structure shown, a 2'6 stem 15 is mounted for rotation Within the rear end of the beam and has a. fork 16 at wheel supported frame and a beam mounted connection extending across the beam, and

to swing horizontally relative thereto, said beam being connected to the frame, of a transverse shaft, spools thereon, flexible elements connected to the spools and to the beam, said elements being extended beyond opposite sides of the beam respectively, I means for rotating the shaft to simultane ously wind one of the elements and unwind the other element, a soil-engaging elementadapted to rotate about an axis extending upwardly through the rear end portion of i the beam, saicl element being movable with the beam, a member movable with said SOll engaging element, and a non-flexible c0n-- nection between one sicleportion of the frame and a point upon said member remote from the axis of rotation thereof, said connection being extended obliquely across the beam.

In testimony that We claim theforegoing as our own, we have hereto affixed our signatures in the presence of two Witnesses.
